SPECIFICATION forming partof Letters Patent No. 296,659, dated April 8.1884,

Application nien october 23, resa.' (No model.:

10 cotton-gins5 and it consists in the peculiar combinations,construction, and arrangement of parts hereinafter described, and thenpointed out in the claims.

The object of my invention is to overcome 15 the great difficulty whichhas always existed in the free and uninterrupted operation ofcottingins, which is to disengage the lint from the gin-saws as fast asdragged off from the boils in the roll-box.n v

which leather and fibrous materials aroused for cleansing ginsaws, someof which are very ef ective; but they require much more intelligentattention than can be usually obtained from with which gin manufacturersand ginners have held to the oldnashioned bristle brush. I havesucceeded in overcoming the difficulties which have hitherto preventedthe universal use of bristle brushes by the construction and arrangementshown in the accompanying drawings, in which- Figure-1 is a side view ofa gin constructed according to my improvement, with part of the casingremoved. Figs. 2 and 3 represent enlarged detail views of the lags,brushes, and portions of the saws, the former being a plan showing thesides of the brushes and the mode oisecurin g the saine, while thelatter shows the same features, looking toward the ends of the brushes.Fig. 4 is a detail view of a portion of lthe combing-boards, showing therelation of the combing-pins with the brushes.

A represents the frame of the gin, and B the saws, which rnay be of anyapproved forni and driven in the usual manner.

C are disks, preferably of wood, secured on a suitable shaft, andprovided with lags D, secured thereto in the usual way. Attached to`mered iiat upon or into the lag, as shown in Several patents have beenlately granted in f the ordinary gin-hand, and hence the tenacity eachof these lags in any convenient manner are the cylindrical brushes E.These brushes are made in the same way as those used for cleaningbottles, lamp-chimneys, &c.viz., by placing a sufficient quantity ofbristles in the opening formed by doubling a wire and then twisting thetwo strands, by means of which the bristles are securely fastenedbetween the Wires and formed into a cylindrical brush. These brushes,having twisted-wire shanks e, forming threads, may be screwed into holesformed in the lags to receive them; or they may be set loosely intoholes-and there held by setscrews F; or the ends of the wire shank maybe untwisted, and then bent and ham- Fig. 2.

Owing to the wear or" the bristles coming on the ends thereof, they willwear a long time; but when partially worn they may be turned slightlyonI their axes, so as to bring a new set of bristles into action, andthis may be repeated several times until the brushes are worn allaround. As the brush-cylinder revolves, the ends of the bristles cornein contact with the sides of the saws, and thus exert their cleaning 7property to the best advantage, and any of the iibers or nietes that mayadhere to them will be knocked off by wires G, set in two rows on thecombing-'board H, as shown in Figs. l and 4, arranged in the mote-box I,and the fibers not dropped below will be driven into the mote-box and begathered there by the force ofthe blast, which passes into said box andescapes through the openings in the ventilating device or wire-gauze J.I prefer to arrange the combing-wires in two rows, the wires of one rowbeing diagonally in line with the wires of the other row, 'as shown inFig. 4, and so arranged that one set of wires strikes the brushes alittle before the other set strikes the adjacent brushes. By thisarrangement -of the bristles and pins, as show-n, the bristles of eachbrush 'strike the pins and are bent, as shown in Fig. 4, and as soon asthe brush has passed the pins the elasticity of the bristles causesthernto assume their original position, whereby two rapid motions are givento the bristles at each revolution, which enables them to throw off anymatter (such as motes) that may be clinging to them, and this isindependent of the jar caused by the striking of the bristles againstthe pins, which also helps to throwoff the motes. I arrange the pins ontwo rows, for the reason that as only half the my improvement is ofgreat value, as my style of brushes will take off all thev gummy matterusually adhering to the saws, and as the bristles necessarily becomecharged with the same'and carry it and the motes or napped cotton withthem until the bristles strike the 2o pins, when they are opened, asshown in Fig.

4, and the bristles thoroughly separated, because as the bristles getout of contact with the pins they immediately iiy back and straightenout with a rapid iiirting motion, and the jars or shakes these bristlesthus get causes them to throw off all matter adhering to them. If itwere not for this jarring or shaking, my bristles would soon becomesurcharged with the naps, gummy matter, sand, Ste., and would 3'o\soonbecome a solid mass of concreted material, which, besides rapidlywearing out and dulling the saws, would create such an amountof frictionon them as to generate heat, electricity, and even flame, which ofcourse should all be avoided in or around a cotton-gin.

Another advantage that my gin has is4 the location of the mote-box,which is arranged above the flue through which the mass of the lintpasses after it is thrown off the brushes, 4o and-that the combing orjarring pins are so arranged that any of the napped cotton which may beshook or knock ed off of the bristles by the jar given to them by theircoming in contact with the pins will fall or be carried into the box bythe current caused by the rapid rotation of the brush-cylinder.

I have shown seven lags or brush-holders on the brush-cylinder; but I donot wish to limit myself to this exact number, as I shall 5o probablygenerally use less, because, owing to the perfection of the operation ofthese brushes, half the number usually employed will do better work.

The advantages of this'invention may be summed up as f'ollows: One-halfof thebristles usually required will be saved; speed of brushcylindercan be reduced one-half; no gumming of saws by damp or immature cotton;no stoppage to clean gin-saws; no napped 6o cotton; more freedom frommotes; more durability of bristles; and, to sum up all, much more andbetter work can be done at less cost. It is evident that cylindricalbrushes may be made of other'materials, such as fibers of whalebone,preparedl rattan, and various grasses, horse and other hair, strips ofstiff cloth, felt, &c. but I prefer the bristles on account of theirwell-known durability.

What I claim as new isl. The combination, in a cotton-gin, of a 7o setof saws with a series of brushes constructed to be turnedV on their axesto bring different sides to bear on the saws, substantially asdescribed.

2. The combination, in a cotton-gin, of a set of saws with a cylinderprovided with a series of adjustable brushes having their acting fibersarranged substantially at right angles to the sides of the saws,substantially as described.

3. The combination, in a cottongin, of a set of saws with a series ofcylindrical brushes having their acting fibers arranged at right anglesto the sides of the saws, substantially as described.

4. In a cotton-gin, a seriesof saws and a series of brushes having theiracting fibers arranged substantially parallel with the rotating shaftcarrying the brushes, in combination with a series of pins pointingsubstantially toward said brushcarrying shaft, and arranged to be struckby the fibers of the brushes substantially at right angles to theirlength, whereby the fibers are first jarred and then caused to iiirtrapidly back to their original position,

las set forth.

5. The combination, in a cotton-gin, and with the saws thereof, of aseries of cylindrical brushes having their acting fibers arrangedsubstantially at right angles to the sides of the saws, and a series ofcombing-wires set in different planes, and also arranged substantiallyat right angles to the acting fibers of the brushes, as and for thepurposes set forth.

'6. The combination, in a cottongin, and with the saws andbrushes-thereof, of the motebox I and the comb G H, arranged in saidmote-box, substantially as described.

7. The combination, in a cotton-gin, of a brush-cylinder, a device,substantially as described, for cleaning the brushes, and a moteboxarranged to receive the refuse removed from the brushes by the cleaningdevice, as

- set forth.

8. The combination, in a cotton-gin, of a brush-cylinder, the pins, aflue to carry away the lint, and a mote -boX arranged above the ilue, toreceive the refuse knocked off the brushes by the pins, substantially asdescribed.

In testimony whereof I affix my signature, in presence of two witnesses,this 8th day of October, 1883.
